Sympathetic Chain Blocks

Sympathetic blocks are treatments available to patients who are suffering from CRPS or chronic pelvic or abdominal pain.

Sympathetic nerve blocks are safe procedures for treating a variety of chronic pain issues affecting different areas of your body. The key to success is in the proper targeting of the nerve that manages the area causing the pain.

Conditions Treated With Sympathetic Blocks

A sympathetic nerve block can be used to diagnose or treat pain involving the nerves of the sympathetic nervous system. Examples of conditions for which a sympathetic nerve block might be used include:

  • Reflex sympathetic dystrophy (RSD)
  • Leg pain and swelling
  • Complex regional pain syndrome (CRPS)
  • Pelvic Pain
  • Abdominal pain

Typical Benefits Of Sympathetic Blocks

  • The goal is to “reset” the spinal cord and brain and interrupt the pain cycle.
  • Less need for systemic opioids (narcotics) and less nausea as a result.
  • Improves mobility.
  • Reduces pain and swelling.
  • Provides pain relief or provides diagnostic support to determine whether pain was originating from the sympathetic nervous system.
  • Very short recovery period.  Patients may return to work the same day or next day.
